BRUSSELS (Reuters) - Belgian police have made a fourth arrest as part of their investigation into Islamist militants suspected of plotting attacks on police, prosecutors said on Wednesday.
Last Thursday police killed two men in Verviers in eastern Belgium during one of several raids against an Islamist group which officials said was about to launch "terrorist attacks on a grand scale".
